Roll Grinding Measurement Solutions|Roll Measurement ...

If T.I.R. is measured at the side of the grinding wheel, after grinding, too good result is recorded because the assembly from the roll to the wheel, to the carriage, to the ways becomes almost "fixed" due to the grinding procedure. The largest T.I.R. reading, or grinding error, shows on the opposite side of the grinding wheel.
